Two commonly confused words are 'affect' and 'effect', with 'affect' being a verb and 'effect' being a noun. 'Affect' means to influence or bring about a change in, while 'effect' is a result or consequence of an action. For instance, excessive smoking can 'affect' your health, and the 'effect' of this can be lung cancer.
